This week in Math 10 we were introduced to polynomials, but only reviewed what we were taught in grade 9. Some things I remember are models, degrees, types, and distributive property,

Example: 5(8x – 3y) + 2(4y + x)

Step 1: Multiply 5 by 8x and then again with -3y

Ex. 40x – 15y + 2(4y + x)

Step 2: Mutiply 2 by 4y and then again with x

Ex. 40x – 15y + 8y + 2x

Step 3: Collect like terms. Add 2x to 40x and add 8y to -15y

Ex. 42x – 7y

FInal Answer- 42x – 7y
